Learning Coordinated Preference for Multi-Objective Multi-Agent Reinforcement Learning

arXiv:2606.14693v1 Announce Type: cross Abstract: Cooperative multi-objective multi-agent reinforcement learning (MOMARL) models team decision making under multiple, potentially conflicting objectives. In this setting, conflicts arise not only across objectives but also across agents with different observations, roles, and contributions. We propose Preference Coordinated Multi-agent Policy Optimization (PCMA), which learns coordinated agent-specific preferences to enable complementary trade-offs among agents. Theoretically, we formulate cooperative MOMARL as a team-optimal game and show that,

Why this matters
Why now

The proliferation of complex multi-agent systems and the increasing focus on AI for real-world decision-making necessitate more sophisticated methods for coordinating diverse objectives.

Why it’s important

This research addresses a fundamental challenge in multi-agent AI, enabling more effective and adaptable teamwork in scenarios with conflicting goals, which is critical for future autonomous systems.

What changes

The ability of AI systems to learn coordinated, agent-specific preferences will improve their capacity to navigate complex, multi-objective environments collaboratively.
